View Full Version : Bimba wait time
first of all i am very appreciative of this company being willing to do so much donating to FIRST Robotics. That being said the build and ship time on our free cylinders will almost make them unusable for this season. ( we ordered the first day website was working. As of today 7-10 days yet tell they get here:(
maybe its the good, fast, cheep ...pick 2 philosophy

Unfortunately, this is true. Bimba's donation is awesome, but it's only real use is to build up an inventory of pistons on the off-chance that they will be used in future years.

Exactly what we do. We get from bimba stuff we think might be useful in the future. What we need now comes from mcmastercarr.
Cylinders we purchase from Bimba do come rather quickly.

Do pistons ordered without the voucher ship in a more reasonable time? Or is it Bimba in general that is very slow?

If I recall correctly, the cylinders we ordered outside of the voucher in 2013/2014 came in about 2 weeks. About half of them had non-standard mounting options, so there's a chance they were assembled after we ordered them from pre-fabbed individual parts - thus the lead time. This seems reasonable to me.

Lead time on standard size pistons is pretty quick. It's really just the voucher that's slow IMO. We ordered some pancake cylinders last Tuesday and had them by Friday.

Good prices to me and worth it to my team.
Or, PHD has some OCG cylinders, but they are not easy to get through a website, you have to locate a distributor in your area.

This might be varied. When we ordered Bimbas before, we had to go through our local distributor. They got them to us in a week.

Hhm, I'm wondering if it is the "made to order" cylinders from Bimba that take a long time to ship. AD there looks to have a bunch of stock cylinders that, if they don't have to produce them after you make the order, could ship out a lot faster. Maybe Bimba's benefit is that you can get nearly any size from them, but you have to wait?

Last year, we ordered cylinders. The 'free' ones shipped from Mexico and took something like 3 weeks. The purchased ones shipped from Chicago and we had them in just a couple days. The cylinders were the same.

I just called and heard back from Bimba, we ordered 1/15 and they hope to ship from Mexico tomorrow (1/30), no delivery information. We need spares anyway so I guess I'll go ahead and order a couple from AD so we can finish assembly.

The cylinders (3/4" bore, 12" stroke, double acting, rear pivot) we ordered from McmasterCarr ended up being Bimbas anyways. They probably aren't all Bimba cylinders, but some are.

For what it's worth, I ordered Automation Direct cylinders yesterday and they will be arriving tomorrow. The offer free 2-day shipping on any orders over $49 and have a fairly reasonable selection: http://www.automationdirect.com/adc/Shopping/Catalog/Pneumatic_Components/Pneumatic_Air_Cylinders/Round_Body_Air_Cylinders_(A-Series) 7/16" bore up to 2" bore. Bimba or McMaster would probably have more selection, but these met our needs this year and were much more inexpensive (around $60 for a 2" bore 4" stroke).

The Bimba donation is one of the best donations FRC teams have been able to get for a long time, IMO.
The inherent problem though is they are costly to stockpile and until teams start build season and designing their robots, its very hard to pre-determine what you need.
We've had this issue for years and would often ask to trade other teams for extra Bimba cylinders in the past.
The easiest solution for us as a veteran team was to strip it off an old robot and put back the cylinder at a later time.:D

We never did receive our Bimba cylinders, I guess I'll call them again.

We just got ours on Friday, and I placed the order on the 22nd of January, three and a half weeks ago.
R 4.1:
A VENDOR is a legitimate business source for COTS items that satisfies all of the following criteria:
C. must be able to ship any general (i.e., non-FIRST unique) product within five business days of receiving a valid purchase request. It is recognized that certain unusual circumstances (such as 1,000 FIRST Teams all ordering the same part at once from the same VENDOR) may cause atypical delays in shipping due to backorders for even the largest VENDORs. Such delays due to higher-than normal order rates are excused.
D. should maintain sufficient stock or production capability to fill Teams’ orders within a reasonable period during the season (less than 1 week). (Note that this criterion may not apply to custom-built items from a source that is both a VENDOR and a fabricator. For example, a VENDOR may sell flexible belting that the Team wishes to procure to use as treads on their drive system. The VENDOR cuts the belting to a custom length from standard shelf stock that is typically available, welds it into a loop to make a tread, and ships it to a Team. The fabrication of the tread takes the VENDOR two weeks. This would be considered a FABRICATED ITEM, and the two weeks ship time is acceptable.) Alternately, the Team may decide to fabricate the treads themselves. To satisfy this criterion, the VENDOR would just have to ship a length of belting from shelf stock (i.e. a COTS item) to the Team within five business days and leave the welding of the cuts to the Team.)
[Blue Box]The intent of this definition it to be as inclusive as possible to permit access to all legitimate sources, while preventing ad hoc organizations from providing special-purpose products to a limited subset of Teams in an attempt to circumvent the cost accounting rules. FIRST desires to permit Teams to have the broadest choice of legitimate sources possible, and to obtain COTS items from the sources that provide them with the best prices and level of service available. Teams also need to protect against long delays in availability of parts that will impact their ability to complete their ROBOT. The FRC build season is brief, so the VENDOR must be able to get their product, particularly FIRST unique items, to a Team in a timely manner.
[/Blue Box]
I find this interesting. Bimba takes more than 2 weeks to ship(they're taking over 3 on our cylinders), so that appears to be "unacceptable" even if they have to custom make the part. Also, if the manufacturer is custom-making a part for a team, it appears to be a "manufactured item" so it might not be exempt from withholding. This rule appears to state that any cylinders bimba has to make custom and by consequence, have not yet shipped, are part of your witholding allowance. It also might be that they are totally illegal.
I don't think they fit under the category of "a bunch of teams want to buy stuff at once" because most teams probably want slightly (or completely) different parts. Also, Bimba is a pretty big company, so FIRST orders can't be much "higher than normal"
However, this doesn't really fit with the stated intent of the rule per the blue box, I just think its funny to call bimba a non-legitimate business. Its sounds like they're some guy on the street selling pneumatic cylinders. I really believe that bimba cylinders are legal and that they aren't part of witholding.
I realize I'm probably lawyering the rules a little too hard, but on the other hand, the rules are pretty clear here.

We placed our order on Jan 28, and received them on Feb 11. Two weeks seems like pretty good turnaround (since they advertised it would be 7-10 business days). We are in Michigan. The cylinders were 1 1/2" bore, 1.5" stroke and 4" stroke.

Our cylinders came yesterday; just in time to save me from ordering / paying for a couple of spares - our first regional isn't until next week.
3/4" bore 12" stroke, ordered Jan 15th. Every time I called they said there were being built in Mexico - I guess they got hit with more snow days than usual this year.
