Following on from earlier interest and feedback in an other forum, I completed an initial trial successfully today as follows.
The section is made up 5 pieces and results in a more accurate profile than the one I made previously, new profile right of the two shown on my car's firewall. One of the sections used previously has been discontinued. I can see the new section will seal the bonnet very nicely, and be quite robust.
Second trial to follow next week with method to make, and pricing indication.

This is looking very good, great job! I'd like to put my name in if there's still room on your 'wait list' of potential customers...

I have made a second sample and most pleased with the result. See following photographs. The new sample is the one on my firewall.
Sample away with an other local PB owner who is very interested, for testing and acceptance.
Following this will post method to make.
Profiles sections are from Paul Beck, and cost of sponge extrusions alone (5 in laminate) based on making 4 at a time per 2m/car is GBP 44.03 FIS NZ to give an idea, plus about 1-1/2 hrs to make each one.
I will email those who have expressed interest already directly.

| I have noticed on a number of P type firewalls that the curvature of the aluminum channel moulding does not match that of the firewall at the top corners. which means that the seal will not sit down fully into the channel at the corners. It is clearly 'original' and is like that presumably becaue the channel cannot be bent to a tighter radius. I did power file the edge of the firewall to reduce the effect which to my eye looked better once the seal was installed but I guess it's a matter of individual preference. Anyone else noticed this? |

Yes you are quite right well spotted. See photos below of my original PB firewall and fit of the the trial fume seal. The seal fits around really nicely. The join line for the raised sections are visible on the corners as shown. I'll seek feedback whether this is OK. My thought was if I make a spare for my car, is to use windscreen sealant mixed with talcum powder to hide the corner join lines, if deemed necessary.

this is finish on seam on corners using windscreen sealant mixed with talcum powder, then dusted with talcum powder when semi dry

Thanks, Rodney, and Keith
I have put you down for the next batch of 4 P Type fume seals, the first batch is sold. Made to order so can confirm delivery once orders confirmed for a full batch of 4.
Will contact you separately with details.
The sump plug spanner is in final stages of testing, and expect to release a batch of 12 blanks to be cut, next week. This would suit all 'later model' sumps which have the 1/2" square hole in the plug. That is L,K,N and P. Once completed, to be advertised on the 'Traders' Forum.
FYI, there are a number of parts in the 'near to impossible to get' category for P/Ns, and am working on plans for reproductions. Many original spec tools are in this category, with most of the tools on offer, period originals rather than originals as used on our MGs.
My upcoming paper on P/N tool-kits will clarify all this. I am writing this paper in the style of an academic research paper and plan to have it completed by the end of the year. |

Does your list of 'near to impossible to get' category for P/Ns include P-Type gearstick turrets?!!

Thanks suggestion Paul
At this stage it includes a repair section for the turret, as I also need one. Does your car need a new one or a repaired one?
My gear lever was popping out on the bottom and getting stuck in second.
Temporarily fixed with a new gear lever from Barry Walker.
Given me an idea though - a post with 'impossible to find parts for P/Ns wish list'
Some of the parts on my list to make as you may have picked up from my various threads and replies are:
P Type fume seals (in production), Late model MMM sump plug spanner (due to start making), PB 30mph warning light (prototyped), MMM dashboard grab handle (prototyped), SF24 Trafficators, SF24 Trafficator Escutcheons (pressed brass), gearchange turret ball socket repair kit, P Type reversing gate |

First seal from from 1st batch of P Type firewall fume seal production shown
Note the bridge for the raised section of the plywood on the corners of the original spec firewall
Orders/interest received for 10-11 so far, 1-2 left in 3rd batch of 4
Let me know if interested, this is the last for now in this round.
Each seal hand assembled by me, and include a spec sheet with background and provenance

Thanks Andrew
Good to hear, the third destined for Australia
Got you down for one, planned for mid May production and dispatch
Be in touch with details by separate email.
Originally had down for N Type too, but since understand that these used another type of seal, interested if you know what type or have a photo?

I don't have the original one.The N has a seal on the firewall to the body and a separate square section one to the bonnet. The former is an L shape which covers the edges of the firewall.... and is unobtainable.....The latter is very easy to source.

Thanks Andrew
Yes I see the footwell on the N Type is boxed in, so it is only the P Type which uses the seal type I am making, and is the single defense against fumes on this model.
Interested in the L shaped rear section for the N Type too. If you would like me to look at it and you can post a photo of an original or a profile shape, I can see if a lamination might be possible. The method I have developed for the P Type seal effectively welds the foam sections together, so the joins are about as strong as the foam sections themselves. Joins would be hardly visible on an L section.
Nice supercharged N Type in the lower photo by the way. Bet this would really fly and be lovely to drive.
Regards
Donald
