123 Dizzy Bracket
123 Dizzy Bracket
Gents
Was part of a recent thread regarding the club potentially fabricating the adapter bracket required to fit the 123 Dizzy.
Did anyone manage to locate the fabrication drawing or obtain an existing bracket so we can get more made.
I know of at least a dozen other club members looking to get hold of a bracket so any updates would be greatly appreciated.
Cheers.
Richard.

Re: 123 Dizzy Bracket
I do not have the drawings anymore. Had a housemove recently and a new computer recently and all physically and digitally garbage has gone or is lost.
I did found a pic of these. Anyone with an original dizzy, 123 dizzy and engineblock can measure the sizes. The 123 dizzy was a crimp fit in the adapter. These you had to heat with a heat gun, slide the 123 dizzy in and you could never get them out again. Importand was the orientation of the ears and the dizzy so mark these first before sliding in the 123 into the adapter.
A little adapter bush was fitted at the bottom what did accept the gear and had it at the correct height.
A man with a caliper and micrometer should be have the sizes within minutes.

Re: 123 Dizzy Bracket
That looks simple enough. If someone has one they can send me I can reverse engineer it.soe8m wrote: ↑Wed Jan 19, 2022 12:49 am I do not have the drawings anymore. Had a housemove recently and a new computer recently and all physically and digitally garbage has gone or is lost.

Re: 123 Dizzy Bracket
I think that’s the issue Mart, no one seems to be able to locate one.
We know Mahesh may of had a spare one but no one seems to be able to locate Mahesh.
Can any Club Member please help at all ???
I am sure as Mart states reverse engineering these should be straight forward, a number could be fabricated and every member of the club could then obtain one.
Come on guys someone must have one.

Over £300 so not cheap.

Re: 123 Dizzy Bracket
I think if I am not mistaken Mart was referring to obtaining the bracket then reverse engineering the bracket.
As the guys have stated an actual 123 Dizzy is circa £300-£400.
There must be a member that has a drawing or a bracket ?

Re: 123 Dizzy Bracket
If you get a 123 Dizzy and a Sprint Dizzy it shouldnt be to hard to make a bracket to suite the 123 Dizzy you would have the sizes, especially as Jerome posted a picture of what it looks like

Flange thickness 0.312 inch
Bolt slots 0.285 (width)
PCD 2.00
Slot width 0.910
Body length 1.405 (The part that fits into the block)
Body outside diameter 1.185
Body inside diameter ? (to suit 123 dizzy)
all you need is the internal diameter of the 1223 Dizzy and allow a few thou for the interference fit

Re: 123 Dizzy Bracket
I have made a drawing, a bit crude and not to BS 308 drawing standards but someone could convert this in to a CAD drawing with the dimensions I have given.
Hope this helps

Re: 123 Dizzy Bracket
I'm not quite reading what you've drawn there Malcolm, maybe because it's a Word file that I'm importing into Mac and things have moved...can you send me a PDF?
