RB5 Brass Bulkhead at last!

[ongbenghui]

Hi Hi,

I would like to have 1 if you can ship internationally.

Can I suggest a 4 x 3mm or 4mm hole be drill between the 4 screw holes to be secure to the chassis. Then, steel grub screw can be use to varies the weight.

The swedish company www.ghea.se, represented by http://www.rymartracing.co.uk/ in the U.K are currently making such bulkheads and other parts for the Ultima as well. Keep a look out.

yes, i had emailed them earlier in the week.. and they said they should have some within the month, great result! cant wait to get the bulkhead, so i can get rid of those silly adhesive weights.

[Dhami1]

any updates ?

my old man has the original plastic kit part at present, so i'm hoping he may have some in a week or so.

[jim76]

I have a couple of prototype parts in the post from my father made using a new jig he has knocked up. I'll verify they fit perfectly then he will be running off a larger batch for me ready for early next week.

These parts retain the original option of 25 or 30deg kick up at the front and remove the need for the thin plastic wafer used in the kit. Each weigh in at around 40g. This weight can be tailored by removing/drilling some of the excess material in the middle of the 4 mounting screws.

These will sell for £22 inc postage.

I was having a discussion in another forum with other folks that the shim might really matter. And the original bulkhead might be 2.5 degree incline.

Trying to understand when you said shim is not neccessary but you still can flip for 25 or 30 degree.

[jim76]

basically the body of the bulkhead is thicker than the kit original by the thickness of the shim, but it still retains the incline so you can swap kick up angles.

i haven't come across anyone that thinks the shim is important, why it couldn't be moulded in the original part i have no idea.

[RogerM]

The shim corrected the hingepin centre height when changing from 25 to 30 degree castor, thus keeping the roll centre correct.

It could not be moulded into the part as there are 2 shims required, one thicker than the other, to correct for both castor options (although why the thiner shim could not have been part of the moulding and then add / remove a thin shim as required is beyond me ... would save on the confusion as to which shim to run with which setting too!!!!!)

[jim76]

sorry, to clarify. Roger is right about the two spacers. What we have done is make the body 0.5mm thicker removing the need for the thinner shim. If you run the car with 25deg kick up you can simply add the thin shim, instead of adding the thicker one. As most people run with 30deg it will make the shims obsolete.

hope that makes it a bit clearer!

[RogerM]

Top man ...... I'll be ordering one if my tennant ever pays their rent!!!!

[jim76]

OK, sorry for delay, my PC was playing silly buggers and had to be re-installed. And to make things worse they have banned Oople at work, disaster. Now i have to earn my salary

Anyway, pics of the first couple of bulkheads. Apologies for quality, have a new camera phone and no idea how to do close ups yet.

As stated, these are a direct replacement for the kit item, and remove the need for the thinner 0.5mm shim. Not sure on exact weight, i will add that tomorrow when i borrow the post office digital scales! The previous version was 40g, so should be pretty similar.

I have another 13 coming early next week. Am happy to ship abroad but it will obviously add a little to the cost. These are £22 shipped in the UK. Can do cheque or paypal (ideally gift payment to avoid fees).

Roger, one of these has your name on if you want it?

[jim76]

thanks for the replies. once i have the additional units in hand next week i will reply to everyone with payment details.
thanks
